Topic on Extension talk:ConfirmAccount

I have followed all the installation instructions, and everything appeared to run smoothly:

• Download and place the file(s) in a directory called ConfirmAccount in your extensions/ folder. - DONE
• Add the following code at the bottom of your LocalSettings.php: - DONE

require_once "$IP/extensions/ConfirmAccount/ConfirmAccount.php"; 

• Run the update script which will automatically create the necessary database tables that this extension needs. - DONE
• Ensure the wiki has write permissions on $wgUploadDirectory, or manually set $wgFileStore['accountreqs'] and$wgFileStore['accountcreds'] to a writable directory of your choice. - DONE
• Done - Navigate to Special:Version on your wiki to verify that the extension is successfully installed. - EXTENSION NOT SHOWN

Does anyone have any ideas of what could be wrong here? Much appreciated.
